D11 Slav Defence: 3.Nf3 sidelines and 3...Nf6 4.e3 Bg4 (1.d4 Nf6 2.Nf3 d5 3.e3 Bg4 4.c4 c6 5.Qb3 Qc7)

The second truly new post today, thought doing another one and also tell of the updated posts that I added games to. The posts I have updated today are Dutch Defense: General and English Opening: King's English Variation. General, they both have now three games to look at. I might still do some of my older posts again since the openings might not be technically correct in some of them, a bit obsessed on things like that sometimes. We shall see if I get into changing them.

Qxa3 21.bxa3 20...a6? 20...f6 21.Bb3 fxe5 21.Qa3 Qg5 21...Qxa3= remains equal. 22.bxa3 f6 22.Rf4 White should try 22.Rc2!± 22...f6 23.Bc2? 23.exf6= and White has nothing to worry.

Intending Qe7 and mate. 34...Qh4+ 35.Kg1 Qd8 Black is pushing. 36.Qd6 36.Qb4= 36...Qxd6 37.exd6 Endgame KB-KB Kf8 37...h4! 38.Kf2 38.g3!= was the only way to keep the balance. 38...h4 39.e4 39.a3 keeps fighting. 39...dxe4-+ 40.Ke3 40.b4 40...Bd7 40...Be6!-+ 41.b3 Bd5 41.Kxe4 41.a4 was called for. 41...Be8 42.Bf5
d7 is the strong threat. 42...Bf7! 43.a3 43.Kd4 43...Bd5+! 44.Ke5? 44.Kf4 might work better. Bxg2 45.Bg6 44...Bxg2 45.Ke6? 45.Kf4 g5+ 46.Kg4 45...Ke8 Accuracy: White = 19%, Black = 37%.
